Rigid duct board insulation is among the most effective insulating materials because of the high r value. This uses boards of insulation that are formed by different synthesizing procedures. These boards are available in handy if large areas will need to become insulated. 

Duct board insulation finds tools from insulating material walls, foundations, roofsand tanks, etc.. Rigid duct board insulation can be found in a number of types based upon the chemical composition and also the way to their synthesis.

Frequent examples have been modeled as expanded polystyrene duct board, polyurethane memory foam as well as polyiso or polyisocyanurate foam. Molded enlarged foam can be called bead plank, that will be cut right out into board by the closed cell enlarged mass of pentane comprising beads. 

Bead duct boards employed in roofs are often thicker compared to those utilized in walls to get higher pressure immunity. These are ideal in regions where the temperature version is high. It needs r value stabilization as it has paid down because of the low conductivity gas, and a process called thermal drift. 

Polyurethane foam delivers the most value, at 7-8 percent of depth whenever it's roughly 6-7 to get polyiso foam and 3-4 for shaped enlarged boards. These experience loss in rvalue as time passes. This may be repaired using the board in combination with representing foils and plaster or metallic bonding. Even though memory can also be an accessible liquid spray form, it is more suitable in its board shape if large areas have to become insulated.
